What people ask about joint soreness

1. In 51 consecutive patients whose hip joint was confirmed as the pain source by fluoroscopically guided intra-articular injection, the pain was NOT where the textbook says. Buttock pain was the commonest referral area (71%), ahead of the traditionally taught thigh (57%) and groin (55%); 22% had pain radiating below the knee and 6% into the foot. Fourteen distinct referral patterns were observed, and referral into the lower lumbar spine did not occur.

2. In 113 patients with end-stage hip disease undergoing hip replacement (patients with coexisting knee or spine pathology excluded), the commonest pain sites before surgery were groin, anterior thigh, buttock, ANTERIOR KNEE and greater trochanter. Pain was also recorded in areas not normally considered hip referral zones: lower back in 21.2%, shin in 7.1% and calf in 2.7%. Low back pain was significantly more common in patients with longer symptom duration. Regardless of pattern, 97.3% reported complete pain relief within 12 weeks of hip replacement.

3. Fifty-one men aged 40-70 with no symptoms in either shoulder had one shoulder scanned by ultrasound to a defined protocol. Abnormalities were found in 96% of them: subacromial-subdeltoid bursal thickening in 78%, acromioclavicular joint osteoarthritis in 65%, supraspinatus tendinosis in 39%, subscapularis tendinosis in 25%, a partial-thickness bursal-side supraspinatus tear in 22% and a posterior labral abnormality in 14%.

4. A EULAR task force of 18 rheumatologists, 3 health professionals, 2 patients and a methodologist defined which joint symptoms, in the absence of any visible swelling, should make a clinician suspect that inflammatory arthritis is coming. Seven parameters survived: symptom duration under one year, symptoms in the knuckle (metacarpophalangeal) joints, morning stiffness lasting 60 minutes or more, symptoms worst in the early morning, a first-degree relative with rheumatoid arthritis, difficulty making a fist, and a positive squeeze test of the knuckles. The combination identified at-risk patients with an area under the ROC curve of 0.92 (95% CI 0.87-0.96).

5. In a structured review of 14 studies covering 6,242 patients with an acutely painful swollen joint (653 with confirmed septic arthritis), no single symptom rules the diagnosis in or out: joint pain was present in 85%, a history of joint swelling in 78%, and fever in only 57%. The most powerful bedside data came from aspirating the joint - the summary likelihood ratio rose with the synovial fluid white cell count, from 0.32 below 25,000/microL to 2.9 at 25,000 or more, 7.7 above 50,000 and 28.0 above 100,000.

6. OARSI's 2019 guideline is the only major osteoarthritis guideline that grades treatments separately for people with disease in MULTIPLE joints. Its Core Treatments for polyarticular OA are arthritis education and structured land-based exercise. Critically, intra-articular corticosteroid and intra-articular hyaluronic acid were Level 1B/2 options for knee OA only and were NOT recommended for hip or polyarticular OA; oral NSAIDs were not recommended at all for people with cardiovascular comorbidity or frailty; and paracetamol/acetaminophen was conditionally not recommended.

7. In the Framingham Osteoarthritis Study, 710 people over 50 with NO radiographic evidence of knee osteoarthritis underwent knee MRI: 89% had 'any abnormality'. Osteophytes appeared in 74%, cartilage damage in 69% and bone marrow lesions in 52%. Prevalence of at least one abnormality was 90-97% in painful knees and 86-88% in painLESS knees.
